Yes i did seen it, and many companies do have one of these Dell series at their stations regardless of the use case (outside of gaming / studio etc). Your comment also confirms this for me, that it is a very good model especially for the price.
While this may not true for this model, but have you try using these displays over displayport? I have noticed this on my Dell it is producing much better color (8bit) and response times once connected from DP.
